WHEEL.

SPECIFICATION forming part of Letters Patent No. 394,511, dated December11, 1888. Application filed March 20, 1888. Serial No. 267,868. (Nomodel.)

To all whom it may concern.-

' Be it known that I, DAVID LEE RUSH, a citizen of the United States,residing at Hazlehurst, in the county of Copiah and State ofMississippi, have invented certain new and useful Improvements in llubsfor Fastening Tires and Filling lVheels; and I do declare the following'to be at'ull, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention has relation to improvements in wheel-hubs; and it hasfor its object to pro` vide a hub capable of tightening the spokes, andconsequently the tire and felly, without the necessity of discon nectingan y of the parts, and at the same time producing a strong and durablewheel. These objects are accomplished by the means shown and illustratedin the accompanying drawings, in which- Figure l is a transversevertical sectional view of a wheel-hub constructed according to myinvention, the parts being all shown in a position to receive thespokesA Fig. 2 is an elevation of the inner' side of one of thehubsections, showing the cone in position on the tubular box. S is aview ot' the cone removed, and Fig. l is a view of one of the movablewedges.

Referring' by letter to the said drawings, A indicates the inner and Bthe outer hub-sections, which together constitute the main portion ofthe hub. These sections are designed to be placed upon atubular box, C,which is externallyv threaded tor the greater portion of its length.

The outer section, B, has its inner end provided with an annularvertical tia-n ge, a, and directly beneath this flange an annularrecess, b, which latter communicates with an annular recess, c, of muchless circular area. The flange a of the section B is provided on itsinner side with lugs d, which extend down in a tapering triangular forniinto the recesses l) and c, and are designed to cooperate with similarlugs, e, on the adjacent face of the section A in forming sockets forthe inner ends of the spokes.

The inner section, A, is provided with an internal annular recess, f,conforming to the recess b in the section B, for the purpose ofreceiving wedges, forming seats for the spokes, as will be hereinaftermore fully referred to. The tubular box C terminates at its outer end inan enlargement., g, recessed, as shown,

which is designed to receive the inner end of a threaded rod or screw,F, which passes through an aperture in the hub-section B, so that thesaid section may be limited in its movements ortixed longitudinally tothe box C.

It will be observed that the box C extends 7-o a sufficient distance atits inner end beyond the hub-section A to receive a nut, G. By thisconstruction it will be seen that by simply turning this nut in onedirection the hubsection A may be moved in the direction of the sectionB, while b v reversing the movement of the nuts the sections maybeallowed to separate.

H indicates a cone provided with a central internally-threaded bore, asmore fully shown 8o in Fig. l of the drawings. This cone is groovedlongitudinally on its external surface, as shown at l, to receive thetapered inner ends or edges of the lugs (l in the hub-sections, andthese grooves l increase in depth and width from the small end to thelarge end of the cone, the plain portions m, formed by the grooves l,furnishing seats for the wedges I, which seat the inner ends of thespokes. It will thus be seen that when the hub-sections have beenslipped 9o upon the cone, so as to bring the inner edges of the lugs dinto grooves Z of the cone, one will be prevented from turning withoutthe other. By having these lugs (l enter the grooves l of the cone H itwill also be seen that the wedges l will be kept in their properrelative positions while being moved upon the plain portions m of thecone.

The wedges I have bevel or inclined sides n,

which engage the plain portions m of the roo cone, and the oppositesides of these wedges are provided about midway of their length This caphas an externallyethreaded 6c with a transverse recess, n practice theseWedges are placed within the annular recesses f and b of the respectivehub-sections and upon the plain portions m of the cone, so that therecesses r of the said Wedges will lie at the base of the spoke-sockets.

By a hub of this construction the tire and felly of a Wheel may betightened Without the necessity of removing either of them, it being 1osimply necessary to turn the parts so as to move the Wedges up theinclined surfaces of the cone.

The hub-section A is provided adjacent to the socketflugs With. anexternally-threaded` I5 portion ,V s, which is designed to receive aninternally-threaded band, so that when it is desirable to secure the twohub-sections together by means of bolts, which may be passed throughapertures T, the band t may be turned 2o up and prevent the said boltsor their nuts from casual displacement.

H avin g described my in ve11tion,What I claim 1s- 1. In a hub, thecombination, With the ex- 2 5 ternally-threaded box, of: thehub-sections recessed,.as described, and provided with the taperingrlugs on their adjacent faces to form spoke-sockets, theinternally-threaded cone having external grooves to receive the inneredges of the socket-lugs, and Wedges having spoke-sockets and arrangedupon the said cone, substantially as specified.

2. In a hub, the combination, With the externally-threaded box, of thehub-sections recessed, as described, and provided With the socket-lugs,the internally-threaded cone arranged upon the said box and havinggrooves on its outer side to receive the inner edges of the socketelugs,the wedges arranged upon the inclined surface of the con eand havingspokesockets, the inner end of the threaded box being extended toreceive a nut whereby the section A of the-hub may be moved upon thesaid box, substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.

DAVID LEE RUSH.
